Phonetic Spelling:hy-poh-KAIR-iss rad-ee-KAY-tuh

Genus:Hypochaeris

Species:radicata

Family:Asteraceae

Cat's Ear, a perennial weed originating from Eurasia and belonging to the aster family, has established itself across every continent except Antarctica. Characterized by a deep taproot and a rosette of leaves at its base, its flowers are often confused with those of dandelions due to their similar wind-dispersed seeds. This plant thrives in a variety of environments, commonly found in lawns, fields, along roadsides, and in any disturbed land.

Adaptable to diverse conditions, Cat's Ear grows well in most soil types, although it typically avoids wetland areas. Each plant can produce a significant number of seeds annually, with the potential for each seed to develop into a mature plant within just two months. In certain regions, it is regarded as an invasive species.
